Briggs Stratton 5hp I/C starts ok, runs, but will not rev

My money is on a partial blockage of the main jet or the passageway to it. You're having to force it to run through the idle jet by fully choking the incoming air. There's not enough gas coming in with the choke open to allow it to run.

I'm thiniking total carb disassembly, carb cleaner and an air compressor combined with a ton of patience will take care of the issue.

Wont idle without choke being used

Main jet dirty. Likely Ethanol fuel fouling. Remove and clean jet. Check all rubber tubing to/from carb for cracks/deterioration and replace.

Hi and welcome to FixYa,

Almost always, the described problem indicates a clogged idle jet. Fix calls for a carb pulldown, cleaning and soaking of non-rubber parts in carb cleaner. A can of compressed air would be helpful in blowing sand, dirt, grit and varnish like film off the components. Exercise care and caution on the small springs, washers, spacers and o-rings. If the air idle mix screw would be removed, count the number of turns from fully in.

Good luck and thank you for asking FixYa.

Runs great with choke on but continues to die when choke is turned off. 2008 ktm 530 exc

Hey mate,

you definately have a problem with your fuel system, I would say you have had some dirty fuel thru your bike, the first thing i would check would be the fuel filter between your tank and the carby then if still does not run drain your carby bowl... after this if it still does not run you will need your fuel system/carb stripped down and flushed would recommend getting this done by a mechanic as there is alot of small parts involved...

Hope this helps

2008 KTM 530 EXC is a bugger to start.

While it's generally considered a cardinal sin to touch the trottle on a thumper while starting. I found my pumpkin liked to have a quick squirt (little blip of the throttle) before trying 1st. Got luck I discovered this after many hours of head scratching.

Only running on full choke?

The jets on the carb need to be cleaned.

Idle adjustment

Hi and welcome to FixYa,

Initially, the "choke" in a 2002 Ducati Sport 900 is not really a choke, it is an idle lever that increases the idling slightly above normal. A real choke would enrich the mixture by adding more gas and limiting the air and is performed by the ECU. This conditioned is triggered by the temperature sensors and kicks in only when cold. Corrective action would then be to adjust the idle RPM.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Start fail

just wondering if anyone can help me. I bought my son a second hand for the christmas of 06 (2005 model). He has not used it since last summer as I have not had the time to take him out on it we both tried starting it the other day without success. I am not a technical man and I cant find anything on starting it. We didnt use the choke, but I am just looking for some help to have it up and running for him, as he has been deprived of it. Thanks very much lads, he and I will both appreciate it!! ,I would pull the plug to make sure its not fouled. If it is then replace it with a new one. Then try starting it. As far as choke operation, pull the choke out, start the bike let i idle for a minute or two, push the choke back in and continue to warm up the motor.,,,
